Spray paint is a quick and easy option for large plastic frames
Before you start spray painting, it is important to prepare the work area. Find an outdoor area to spray paint, preferably in the shade. If you cannot work outdoors, make sure to cover the ground with a tarp or cardboard and cover any areas that may be hit with overspray with painter's plastic or a drop cloth. Anchor each corner of the tarp or plastic so that it does not blow onto the frames.
Next, you will need to prepare the frames for painting. Clean the frames with hot or warm soapy water to remove any dirt, dust, grease, or debris. You can also use a degreasing dish soap for this step. Once the frames are clean, dry them thoroughly.
When you are ready to paint, hold the spray paint can about 2 feet away from the frame and spray in a back-and-forth motion. Spray the back edge of the frame at a 45-degree angle so that the paint hits the top and backside at the same time. Let that coating dry completely, and then do the same from the front so that you get the lip and top at the same time. Having the frame raised will help eliminate any drip lines and spray bounce.
After you have sprayed one side of the frame, walk down one side, let the paint dry for 15 minutes, and then walk down the other side. This will help eliminate build-up in the detail and allow the paint to settle into the detail. You may need to apply multiple coats of paint, depending on the desired coverage.

Use a quality bonding primer to make paint stick to plastic frames
Painting plastic can be challenging as standard paints don't stick well to its smooth and non-porous surface. To ensure that your paint adheres to a plastic surface, you should use a quality bonding primer.
A bonding primer will improve adhesion and durability, and provide a great base for an even finish. Benjamin Moore's Insl-X Stix is a highly recommended waterborne bonding primer that can be used on a range of surfaces, including plastic. It is designed to bond to difficult-to-coat surfaces and can be top-coated with almost any product.
Before applying the primer, ensure that the plastic is clean, dry, and free of any surface contaminants such as dirt, grease, oils, and waxes. You can wash the plastic with warm, soapy water and a soft sponge, and then let it dry completely.
Once the plastic is clean and dry, you can apply the primer. Insl-X Stix can be applied with a brush, roller, pad applicator, or airless spray. Use a high-quality nylon brush or a 1/4"–1/2" synthetic nap roller cover. Apply a thin, even coat and let it dry completely before painting. The recoat time for Insl-X Stix is 3-4 hours, and it takes 3-4 days to fully cure.

Chalk paint gives substance to plastic frames, making them look less cheap
Painting large plastic frames can be a great way to upcycle them and make them look less cheap. One paint option that can be used on plastic is chalk paint, which gives a matte, chalky finish to any surface. It is ideal for creating vintage, shabby chic, and rustic effects.
Chalk paint is a versatile paint that can be used on a variety of surfaces, including plastic. It is easy to apply, dries quickly, and does not require priming or sanding beforehand, making it a convenient option for those looking to avoid extensive prep work. Additionally, chalk paint sticks easily to most surfaces, and only one coat is usually needed.
For plastic frames, chalk paint can be a great way to give them substance and make them look more expensive. The paint adds a layer of thickness and texture, transforming the appearance of the plastic. With chalk paint, it can be difficult to tell that the frame is made of plastic at all, as it can resemble a wooden frame.
To achieve the best results with chalk paint on plastic frames, it is important to ensure that the surface is smooth, dry, and clean before painting. While chalk paint does not typically require a primer, using one can help the paint adhere better and create a more durable finish. After painting, a coat of varnish can also be applied for added protection and to achieve a desired level of sheen.

Sanding and priming are important steps to ensure paint doesn't scratch off
Painting plastic can be tricky as the paint tends to drip, pool, and blotch, and once dried, it can quickly peel off. To ensure that the paint job is long-lasting and scratch-resistant, it is important to prepare the plastic surface adequately. This includes crucial steps such as sanding and priming.
Sanding is an essential step in preparing plastic for painting. Most plastic surfaces have a glossy finish, which can hinder paint adhesion. By sanding the plastic, you create a rougher, matte surface that the paint can better adhere to. Use a fine-grit sandpaper to scuff the surface lightly, ensuring you don't damage any intricate details or lines on the plastic frame. After sanding, wipe down the surface with a damp cloth to remove any dust or debris.
Priming is another critical step to ensure the paint adheres well and doesn't scratch off easily. A quality bonding primer is recommended, such as Benjamin Moore INSL-X Stix. Apply two thin layers of primer, allowing each layer to dry completely before adding the next. This helps create a durable base for the paint to stick to and reduces the chances of chipping or scratching.
If you are using a spray paint specifically designed for plastic, you may not need to prime. However, if you opt for regular spray paint, priming becomes necessary to ensure proper adhesion. Additionally, always ensure your work area is well-ventilated when working with primers and paints to avoid inhaling fumes, which can cause headaches, dizziness, or nausea.
By properly sanding and priming the large plastic frames, you can create a surface that the paint can effectively adhere to, resulting in a long-lasting and scratch-resistant finish. These steps are crucial in ensuring the final painted product is durable and aesthetically pleasing.

Varnish can be used to protect the final paint job and add a matte finish
Painting large plastic frames can be a great way to give them a new look. Once you have painted your frame, you can use varnish as a final step to protect your paint job and add a matte finish. Varnish is a clear liquid coating that can be applied on top of paint to enhance and protect the final product. It serves two primary purposes: protecting the surface and enhancing the overall look.
Varnish protects the paint job by creating a protective barrier that prevents chipping and paint rubbing off. This is especially important for surfaces that are often handled, as it helps to preserve and protect your work from wear and tear. Additionally, varnish can also be used to achieve different effects and finishes. Depending on the type of varnish, you can add depth, enhance colour vibrancy, or create specific effects like wetness or shine. Matte varnish, for example, removes the shine from paint and creates a flat, matte finish, making it ideal for achieving a realistic, non-glossy look.
When choosing a varnish, you have several options, including matte, satin, and gloss. A matte varnish will give you a flat, non-glossy finish, while a gloss varnish will provide a high-shine, glossy finish. If you're looking for something in between, a satin varnish offers a good middle ground with some sheen but without the intense reflectivity of a gloss finish. This type of varnish is versatile and works well for most projects, especially if you want to highlight texture and depth without going too matte or too shiny.
It is recommended to test the varnish on a small area first, such as a piece of cardboard or an old miniature, to ensure that it aligns with the look and effect you desire. Additionally, it is important to allow adequate time for the varnish to cure fully between coats, ensuring the best possible protection and finish. If any parts are uneven, you can always add a second thin coat.

To get paint to stick to a plastic frame, it is recommended to use a quality bonding primer like Benjamin Moore INSL-X Stix. Clean the frame, scuff sand it, clean it again, and then apply the primer.
To create a distressed look, first, paint the frame with a coat of dark brown paint. Then, use your finger to rub petroleum jelly on the parts of the frame you want to look distressed, such as the edges and details. Paint three coats of white paint and let it dry. Use a damp paper towel to gently wipe the frame, wherever there was petroleum jelly, the paint will wipe off, leaving a distressed finish.
